BALlNG-PRESS.

SPECIFICATION forming part of Letters Patent No. 387,486, dated August '7, 1888.

Serial No. 270,292. (No model.)

To all whom it may concern.-

Be it known that we, HENRY F. BLANK and HENRY W. SCHWARZBURG, citizens of the United States,residing at Quincy,in the county of Adams and State of Illinois, have invented new and useful Improvements in Baling- Presses, of which the following is a specification.

Our invention relates to that class of portable presses for baling hay, cotton, and other material, and for various other purposes, in which a plunger is driven by a horse-power continuously acting in one direction through the rotation of a sweep.

One object of our invention is to provide means for automatically increasing and diminishing the leverage of the plunger-actuating mechanism to correspond with the require ments of the operation of pressing.

Another object of the invention is to provide an automatic feeding mechanism that is operated by the pressingplunger; and the invention has for a further object the construction of a horse-power press in which the horsepower mechanism is supported on a power-sill attach ed to the forward axle of the press-frame and'snpported beneath the press-body for facility of transportation, but capable of being withdrawn with the forward axle when it is required to arrange the press and horse-power for operation. These objects are accomplished through the construction and combination of devices hereinafter described, and illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of our improved portable horse-power press arranged for transportation. Figs. 2 and 2 represent a vertical longitudinal section of the press and horsepower arranged for operation. Figs. 3 and 3 show a plan view ofthe press and horse-power. Fig. 4 isadctail section on the line a mof Fig. 1, and Fig. 5 is a detail view of the scroll-gear.

The numeral 1 designates the rear axle of the'pressframe. On top of the axle are secured two cross-blocks, 2, to which the lower longitudinal press si-lls, 3, are fastened. The forward axle, 4, is connected by a king-bolt, 5, with the forward enlarged end of the horsepower sill 6, which is adapted to be moved forward and back beneath the press-frame. \Vhen moved back, it can be secured beneath the press-frame, as hereinafter explained, for transportation, and when drawn forward the horse-power mechanism mounted on said sill is brought into position for operating the press-plunger.

Near the forward ends of the longitudinal sills 3 are located a pair of stout struts, 7, one on each side of the press-frame. These struts 7 assist the vertical side braces, S, in supporting the upper longitudinal side bars, 9, and also afford a firm support for the mechanism, hereinafter described,thatsustainstheplungeractuatinglevers. Thelower sills, 3, and upper side bars, 9, may also be connected by vertical tie-rods 10, and the struts 7 and side braces, 8, can be connected by horizontal tie-rods 11, if desired.

To the forward end of the press frame, preferably to the struts 7, is pivoted a swinging frame, 12, which consists of the pivoted bars 13 and a connecting cross-bar, 14, secured to their lower ends. This swinging frame 12 is of sufficient length to rest on the ground when lowered and support the forward end of the horizontal press frame when the forward wheeled axle is detached, together with the powersill, and drawn forward to carry the horsepower into operative position. When lowered, the swinging frame 12 is braced and held erect by stops 15 on the lower sills, 3, in front of said frame and by pivoted brace-rods 16, having hooked ends that engage fastenings 17 on the sills at the rear of the swinging frame.

The rear end of the power-sill 6 is mortised on its under side to engage a corresponding mortise, 18, in the upper side of the crossbar 14E of the frame 12, which thus affords'an abutment for the rear end of the horse-power. A strap, 19, is pivoted to the cross-bar 14 in position to extend across the rear end of the powersill 6 and is fastened by a bolt and handnut, 20, so as to be readily unfastened and swung to one side when the horse-power is to be moved back beneath the press. The rear end of the horse-power sill may be steadied against the pull of the horse-power mechanism by means of a bail, 21, suspended from a crossbar or bolster, 22, that connects the forward ends of the press-sills. This bail 21 has its upper ends passed through the bolster 22 and threaded to engage nuts 23 on the upper side of the bolster. The bail 21 extends down in a forwardly-inclined position beneath the sill 6 and in front of pins or lugs 24, projecting laterally from the edges of the sill, thus bracing it against lateral as well as endwise movement. When the horse-power mechanism is drawn forward for operation, the wheels of the forward axle,4,can be detached, so asto bring the power sill 6 into a horizontal position, or the same result can be attained by sinking the forward wheels into the ground a suificient distance. The power-sill 6 is then steadied on the axle 4 by means of hooked rods or clips 25, and stakes can be driven into the ground adjacent to the axle and sill at suitable points for the purpose of preventing any movement of the sill or horse-power support.

On the forward end of the horse-power sill is a stationary vertical post, 26, that forms a pivot forau S shaped variable gear, 27, having two cogged portions, 28, that occupy about three-fourths of its periphery and are separated by two plain or uncogged portions, 29, that constitute the other fourth. The upper surface of this gear 27 is formed with a projeeting hub, 30, which surrounds the post 26, and is in turn surrounded by a socket or collar, 31, on the pivoted end of a sweep, 32, to the other end of which is secured one end ofa pull-rod, 33, which has its other end passed through an opening, 34, in alug, 35, that is se cured to the upper surface of the gear. The end of the pull-rod 33, adjacent to the perforated lug 35,is screw-threaded for attachment of a not or nuts, 36, by which a pulling action is exerted on the lug 35, so as to rotate the attached gear 27 when the sweep is turned.

The S-shaped or variable gear 27 meshes with a small variable scroll-gear, 37, that is pivoted on the horse-power sill, a socket, 38, being provided in the sill to receive a hollow hub, 39, on the under side of the scroll-gear, which is held in place by a screw-bolt, 40, passed through its center. About th ree-fou rths of the scroll-gear 37 is cogged, and the other fourth forms a straight uncogged portion, 41, which corresponds with the uncogged portions 29 of the larger variable gear. The cogged portion of the scroll-gear 37 is preferably formed on its upper surface with a flange, 42, that laps over the gear 27 and prevents any tendency to vertical displacement under strain.

A bifurcated toggle-arm, 43, projects horizontally from the scroll-gear 37 on the side opposite to its uncogged portion 41 and in line therewith. This toggle-arm 43 may be either integral with the gear or detachably secured thereto in any suitable manner, and rotates with the scrollgear when the horsepower is in operation. The outer end of the rotary toggle-arm 43 is pivotally connected to a vibratory toggle-arm, 44, the other end of which is pivoted to a slide-bar, 45, which is supported in aguide-slot, 46, formed longitudinally inthe power-sill. The edges ofthisguideslot are provided with metal wearing-surfaces, and similar surfaces are arranged beneath the gears.

The rear end of the slide-bar 45 is detachably pivoted, by means of a bolt and nuts, 47, to one end of the principal plungerlever 48, the other end of which is pivoted to hangers 49, that are pivotally suspended from a crossrod, 50, supported above the struts 7 in the upper forward part of the press-frame. The rear end of the main plunger-lever 48 is also connected by parallel bars 51 to the end of a lever, 52, that is pivoted in the recessed and slotted end of a horizontally-movable plunger, 53, which is suitably supported in the pressframe. The pivotally-eonnected ends of the bars 51 and inner plunger-lever, 52, are supported by hangers 54, that are pivoted to the inner sides of the struts 7 and swing together with the hangers 49, bars 51, and plunger'levers 48 and 52 when the horse-power is operated.

The horses for supplying the power are hitched to the sweep 32 in any convenient manner; and it will be seen that the horsepower sill 6 is so close to the ground that it will afford no obstruction to the animals. It will also be seen that the variable gears 27 and 37 are so proportioned and arranged as to cause two strokes of the plunger 53 during each revolution of the sweep, the small gear 37 being rotated twice for each rotation of the large gear 27,to which the sweep is connected. When either straight uucogged portion 29 of the large gear 27 is parallel to and in contact with the straight uncogged portion 41 of the small gear 37, the plunger will be projected to its farthest extent into the baling-chamber 55, and as the rotation of the sweep continues the more abrupt portions of the gears 27 and 37 come into meshaud retract the plunger,

with a quick movement. It will also be apparent that, owing to the form of the gears 27 and 37, as shown, the movement of the plunger toward the baling-chamber willcommence quickly and will gradually diminish in rapidity, so as to exert its full pressing force withoutjar or strain. As the sweep 32 is loosely pivoted on the hub 30 of the gear 27 and has its pnll-rod 33 loosely connected with the lug 35, the 1ug-opening 34 being enlarged to permit a suitable play of said rod, it is obvious that said sweep will be turned without strain on the gears. If desired, the sweep may be provided with a brace, 56, as shown.

The bailing-chamber 55 may be of any suitable or well-known construction. At the upper part of its entrance is arranged a folding device, which preferably consists of a roller, 57, journaled in bearings that are supported by springs 58, so that the roller can have a yielding upward movement against the pressure of the material forced into the baling-ehamher, and at the same time roll the loose part of material inward in such a manner as to enable the bale to be formed with smooth and even edges. The bottom of the feed-chamber 59 is provided with a perforated plate, 60, for the escape of hay-seed, dirt, and other extraneous substances, and the perforations in this plate may be so arranged as to form the name or trade-mark of the press manufacturer.

Above the feed chamber 59 is a hopper, 61, through which hay or other material is introduced. In the lower part of this hopper 61 isa non-yielding feedroller, 62, and a yielding roller, 63, having, respectively, sprocketgears 64 and on their ends.. The roller 62 is journaled directly in the hopper, while the roller 63 isjournaled in eyes 66, formed in the ends of horizontal rods 67, that are supported by the press-frame and provided with springs 68, whereby the roller 63 is capable of a yielding movement horizontally to and from the other feed-roller. Both rollers, 62 and 63, are preferably corrugated or fluted longitudinally to facilitate the feed, and the folding-roller 57, near which they are placed, may also be fluted. On the under side of the plunger 53 is a cogged rack, 69, which gears with a pinion, 70, on a shaft, 74 journaled beneath the feedchamher. This shaft 71 has secured to it a ratchet-wheel, 72, which is adapted to engage a spring-pawl, 73, carried by a large sprocketwheel, 74, that is loosely mounted on the pinion'shaft. A sprocket-chain, 75, connects the sprocket-wheel 74, with the roller-sprockets 64c and 65, being held to its engagement with the sprocket 65 by means of an idler, 76, so that as the large sprocket-wheel is rotated the feedrollers 62 and 63 will be turned inward and toward each other in such a manner as to pass the hay or other material into the feed-chamher. This action of the feed-rollers 62 and 63 takes place, however, only while the plunger 53 is being retracted, because the pawl 73 and the teeth of the ratchet-wheel 72 are so arranged that during the pressing movement of the plunger the ratchet-teeth will slip by the pawl 73 without actuating the large looselymounted sprocket wheel. The manner in which the roller 63 is mounted enables it to yield to the passage of the hay into the feedchamber and,together with the roller 62,exerts a sufficient degree of speed and compression to facilitate the feed and somewhat compact the material.

The operation of the press and its connections will be readily understood from the foregoing description.

In preparing the pre:s and horse-power for transportation the slide-bar 45 and main plunger-lever 4.8 will be disconnected by removing one of the nuts 47 and withdrawing the pivotbolt that connects said parts. The plunger 53 will then be moved toward the balingchamher and the free end of the lever 48 raised and rested on the bolster 22 at the forward end of the pressframe. The hand-nut 20 will be loosened and the strap 19 turned backward and to one side, thereby unfastening the rear end of the power sill 6 from the crossbar 14 of the swinging frame 12, thus enabling the rear end of the horse-power sill 6 to be lifted onto an inclined plane, 77, that is hinged to the rear axle. This inclined plane 77 is formed with flanged sides 78.. Its rear end is hinged to the rear axle. 1, and itsforward end rests on the ground when the machine is not ready for transportation. The horsepower sill 6 being, now unfastened in the manner described and the slide-bar 45 and vibratory toggle-arm 44 being also disconnected, the stakes adjacent to the horse-power sill will be withdrawn, the horses will be hitched to the front axle, the forward wheels will be lifted from the pits in which they were placed, and the rear end of the power-sill will be lifted over the cross-bar lat while the horses are backed, thereby bringing the rear end of the horse-power sill onto the inclined plane 77, and then as the horses continue to back, the horsepower sill will be moved upward and backward along the inclined plane 77 between its sides 78,which act as guides until the rear end of the horse-power sill is passed over the rear axle, 1, between the blocks 2 and lower sills, 3, of the press frame. Before moving the horse-power sill backward the brace-rods 16, that confine the swinging frame 12, should be disconnected from the fastenings 17.and the press body moved slightly forward to give 'the swinging frame 12 a slight backward tilt. After the horse-power sill has been moved back beneath the press-frame the forward end of the hinged inclined plane 77 will be raised and the frame 12 will be swung back in an inclined position, with its cross-bar 14: beneath and in contact with the under side of said inclined plane. The brace-rods 16 are hooked to pins or fastenings 79 on the upper side bars, 9, of the press-body, thereby supporting the swinging frame 12 and the forward end of the inclined frame away from contact with the ground. The forward axle, 4:, now supports the forward end of both the horse-powersill and the pressbody, and the horsepower sill is connected with the bolster 22 by means of a vertical pin, 80, supported in said bolster and through which draft is exerted on the press-frame. Before pushing the horse-power sill and its attached mechanism backward the sweep will be turned slightly outward and can be fastened on the right-hand side of the machine in any convenient manner. The bail 21 can be supported from the ground by any suitable means, and the machine as now arranged can be conveniently transported, and is capable of being put in shape for operation without delay or difficulty.
